Translation should be easier than flash. Heck, drop Bepinex and XUnity.AutoTranslator in the game folder and you've already got machine translation. (And also makes text files that you can edit for manual translation.) Downside is you've got to play through the game so that it can dump all the text you want to translate. Icevail has already shown off a bit in the translation thread...
Uncensoring, probably harder. AutoTranslator also includes a module to dump/replace textures. I set it dumping as I played through the game and it's pretty easy to spot the pixelated genital textures. However, I think there's an additional mosaic on top of those that I didn't see a texture for, so it must be implemented some other way. It may require code diving (decompiling) to find and then a Bepinex plugin created to disable. The good news is that the textures looked pretty generic (and the mosaic probabily is too), so once solved for this game will probably work just as well for future games.
Which reminds me: If that doesn't work, you might also be able to set Unity's built in framerate limiter using this plugin:

Actually, nevermind. The legend ManlyMarco has already done the work for us:

I just tried it, and his "DumbRendererDemosaic" plugin works fine, mosaic gone.
Now we just need some generous soul to redraw the textures... (You don't want me to attempt that, my artistic skills stop at stick figures.)
